Sony Clie NX80v and GPS kits

[geo]

Hi,
I wish someone could help me.
I have been using a Sony Clie NX 80V(no blue-tooth) for quite a while now. I find it an indispensible tool for me; it has been great in all departments except one. The problem I have is that I am not sure about a suitable GPS kit (hardware and software) for this handheld. I dont want to dump my clie and go for another expensive alternative.Would anyone be kind enough to advise?
I came across a via michelin route planner with a wired GPS receiver for Clie on offer. Is that good enough? I personally would have preferred Tom Tom 3, with its post code navigation option (I live in UK).
I hope someone was in this situation before and sorted it out succesfully.
Many thanks
Geo
